What does "sigil" mean?

My first instinct was to tell you that it has something to do with role play gaming ... however this is what it's meaning is .....

Pronounced si-jil, it is a noun and is derived from Middle English sigulle, from Latin sigillum.
Dated : 15th century
meaning :
1 : SEAL, SIGNET
2 : a sign, word, or device held to have occult power in astrology or magic

A seal; a signet.
A sign or an image considered magical.

[Latin sigillum, diminutive of signum, sign. ]


A seal; a signature


Definition: The word sigil means a seal or device, but the word usually denotes a magical sigil, a glyph used in ritual or sympathetic magick as a focus. There are several methods of devising sigils for this use, usually involving special arrangements (planetary squares, Enochian tables, etc.) of letters or numbers, and tracing the desired word over this pattern to reveal a symbol (the detailed center of the Golden Dawn Cross is such a pattern), or reducing alphabetical characters into a single glyph.
